Stephen O'Donnell commented on HDDS-1622:
-----------------------------------------
In researching this issue, the current version of PicoCLI used in HDDS is
3.5.2. Some new features have been added to Pico CLI in later releases to allow
commands with sub-commands to be created more easily, notably allowing
sub-commands to be created as methods. I have opened HDDS-1645 to consider
bumping the Pico CLI version to the latest release to let us take advantage of
these features.
> Use picocli for StorageContainerManager

> Key: HDDS-1622
> URL: https://issues.apache.org/jira/browse/HDDS-1622
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Elek, Marton
> Assignee: Stephen O'Donnell
> Priority: Major
>
> Recently we switched to use PicoCli with (almost) all of our daemons (eg. s3
> Gateway, Freon, etc.)
> PicoCli has better output, it can generate nice help, and easier to use as
> it's enough to put a few annotations and we don't need to add all the
> boilerplate code to print out help, etc.
> StorageContainerManager and OzoneManager is not yet supported. The previous
> issue was closed HDDS-453 but since then we improved the GenericCli parser
> (eg. in HDDS-1192), so I think we are ready to move.
> The main idea is to create a starter java similar to
> org.apache.hadoop.ozone.s3.Gateway and we can start StorageContainerManager
> from there.
